Some ideas you might try: The legs bother me as they look like stumps. I would extend the legs up the background and stretch them out. Crossing them at the knee would give her more of an "hourglass" figure. Also, the ceneter of interest, her face, is not at a powerful spot in the composition. Try using the law of thirds or the golden mean theories on the cropping. Finally, I would either angle her body more or make sure it is exactly perpendicular to the film plane. Angled would be more flowing and feminine. Perpendicular and symetrical could be powerful.
